No one knows for sure what dark matter is. But we know we need something to explain what we see in the universe, and we’ve crossed a few ideas off of our list.

What does it take to publish a scientific analysis in one of the world’s largest experiments? A huge amount of meticulous work and scrutiny goes into each paper published by CMS, a collaboration of about 3,000 scientists.
A collaboration of the Americas aims to take the first pioneering images of low-energy neutrinos and provide new data to shed light on the mysterious identity of dark matter.
Hadrons count among their number the familiar protons and neutrons that make up our atoms, but they are much more than that.
The discovery of the muon originally confounded physicists. Today international experiments are using the previously perplexing particle to gain a new understanding of our world.
We know that neutrinos aren’t massless, they’re just incredibly light — a million times lighter than the next lightest particle, the electron. And they don’t seem to get their mass in the same way as other particles in the Standard Model.
A sourdough family started at Fermilab by a graduate student visiting from Texas A&M has continued to expand and flourish.
Physicist Cristiano Galbiati shifted focus from the search for dark matter to the shortage of ventilators for COVID-19 patients. The collaboration he began created an easy-to-manufacture ventilator in less than two months.
New results from the T2K experiment in Japan rule out with 99.7% confidence nearly half of the possible range of values that could indicate how neutrinos behave compared to their antimatter counterparts.
What if you want to capture an image of a process so fast that it looks blurry if the shutter is open for even a billionth of a second? This is the type of challenge scientists on experiments like CMS and ATLAS face as they study particle collisions at CERN’s Large Hadron Collider. An extremely fast new detector inside the CMS detector will allow physicists to get a sharper image of particle collisions.
